"PH meters are slightly more complex equipment to use than traditional indicators, since for their correct use it is necessary to calibrate them and give them constant maintenance. The truth is that once they have been calibrated, the best thing is that they offer an unmatched precision much greater than that of a measuring strip. The PH meter is very easy to use once it has been calibrated, the digital marker accurately indicates the level of acidity or basicity that a certain chemical product has or any other element in which you want to know this element. The reading given by PH meters is less subjective than the reading given by indicators or the reading given by PH strips. The truth is that with the meters, the reading is more precise, since the machine is in charge of determining the level of acidity or basicity, being very precise. We must say that one of the most notable elements of the PH meters is that they are not disposable, but that they are very modern machines that have a very long useful life, it is only necessary to carry out maintenance checks to avoid the calibration be the wrong one. Los medidores de PH son equipos un poco más complejos de utilizar que los indicadores tradicionales, puesto que para su correcto uso es necesario calibrarlos y darles mantenimiento constante. Lo cierto es que una vez que han sido calibrados, lo mejor es que ofrecen una precisión inigualable mucho mayor que la de una tira medidora. el medidor de PH es muy sencillo de utilizar una vez que ha sido calibrado , el marcador digital indica con precisión el nivel de acidez o basicidad que tiene cierto producto químico o cualquier otro elemento en el que se desee conocer este elemento. La lectura que ofrecen los medidores de PH es menos subjetiva que la lectura que ofrecen los indicadores o la lectura que ofrecen las tiras de PH. Lo cierto es que con los medidores, la lectura es más precisa, pues la máquina es la encargada de determinar el nivel de acidez o basicidad, siendo muy precisa. Debemos decir que uno de los elementos más destacables de los medidores de PH es que no son desechables, sino que se trata de máquinas muy modernas que tienen un tiempo de vida útil muy prolongado ,sólo es necesario realizar revisiones de mantenimiento para evitar que la calibración sea la incorrecta."

"Perfect product"

"We have had the two pH meters for just over two years now and they have worked quite well. We have numerous samples coming into the lab, so it helps that the measurements are quick. We heavily rely on the pH meter for factory control and have found the results reproducible and hence reliable. It is very critical for contamination control that the instrument be accurate. We have struggled a bit with the three-point calibration and were advised to use the two-point calibration instead. Other than that, no other issues have been faced since purchasing the instruments. The interface is use friendly, therefore easy to teach to your staff. The instrument does not take a lot of space on the benchtop making it easy to work around. The instruments have not been majorly faulty prior and after sales care, a solid 8/10. The turn-around time is excellent."

"We have 30 pH METERS that were purchased around 12 years ago mainly for our 1st year chemistry students at UKZN. The product is student-proof and very robust as our students are mainly from rural schools and they have very little laboratory experience. In effect, the equipment is exposed to students that have not seen a pH meter in all their school career. I have only recently ordered one spare electrode as a backup. The meters are reliable, easy to calibrate and the plastic electrode always store well when not in use. Ease of use is 10/10, value for money is 10/10, and after sales care is 10/10 as they don't need much. Reps from other companies cannot convince me to change my mind.
